Rotax 912
Rotax 912 štiritaktni bencinski letalski motor avstrijskega proizvajalca ROTAX. Štirje cilindri so v protibatni (bokser) konfiguraciji. Hlajenje je kombincija vodnega in zračnega. Velike obrate motorja znižuje reduktor. Največ se uporablja za ultralahka, športna in brezpilotna letala. Gorivo je navaden avtomobilski bencin, lahko pa tudi letalski becin Avgas 100LL.
Razvoj
urediSprva zo razvili 80 KM motor z delovno prostornino 1211 kubičnih centimetrov in kompresijo 9,1:1. Potem so razvili model 912S, ki razvija 100 KM in ima prostornino 1352 ccm in večjo kompresijo 10,4:1, masa motorja se je povečala le za nekaj kilogramov. 100 KM verzija se uporablja v letalih kot npr. Flight Design CTSW, Tecnam P2002 Sierra in Titan T-51 Mustang. 80 KM se uporablja v Pipistrel Sinusu in Urban Air Lambada.
Motor se razlikuje od npr. zračno hlajenega Lycoming O-235, da ima vodno hlajene glave, avtomatski sistem dovajanja goriva, manjšo delovno prostornino, večjo kompresijo in reduktor z razmerjem 2,43:1. 5800 obratov motorja se zniža na okrog 2400 obratov propelerja. 912 ima dva vplinjača, na nekaterih različicah pa elektronski direktni vbrizg goriva. 912 je tudi okrog 40 kilogramov lažji od O-235 in ima manjšo porabo goriva. 912 uporablja črpalko za olje t. i. Dry Sump sistem isto kot O-235.
Sprva so imeli motorji 912 krajše čase med kompletnim renoviranjem (ang, TBO: Time Between Overhaul), najprej 1200 do 1500 ur, kasneje pa so povečali na 2000 ur.[1].
Marca 2012 je družba oznanila novo različico 912 iS: 100 KM verzijo z direktnim vbrizgom in elektronskim krmiljenjem.[2] Imela bo 2000 TBO.
914 je močnejša verzija z 115 konji.
Barve ohišja cilindrov označujejo moč motorja: črna 80 KM, zelena 100 KM in rdeča 115 KM.
